Pesticide residues variability and acute dietary risk assessment: a consumer perspective.

In relation to residue variability and acute dietary intake, this paper considers whether or not consumers are adequately protected, and makes recommendations for governments and international bodies. Existing risk assessment science is inadequate to lay to rest some concerns raised by the scientific community, and it is plausible that acute exposures to pesticides from the most contaminated food may be causing adverse effects in some consumers. Consumers International recommends that: (1) analysis and regulation of pesticides with a common mechanism of action (e.g. organophosphate insecticides) be conducted in an integrated, aggregated manner, not on a single pesticide basis; (2) exposure to pesticides in foods consumed in large amounts by children be reduced by revising good agricultural practices; (3) clear risk assessment policies for acute risk assessments be established at the national and international level; and (4) an additional safety factor be applied in order to protect children when establishing maximum residue limits (MRLs) for pesticides in the absence of reliable data on the effects of pesticides on children (e.g. no pesticide-specific tests on immature animals for effects on the developing brain, endocrine, or immune systems).
